During the expedition, the team observed evidence of submarine landslides at a number of different scales and locations via remotely operated vehicle Deep Discoverer. Some top geology highlights included the first look at a likely recent event, possibly related to the deadly 1946 tsunamigenic earthquake, and landslide headwalls and extensive areas of mass-wasting on the walls of Noyes Canyon, less than 10 miles from the Queen Charlotte fault and the epicenter of the 2013 earthquake, which had a magnitude of 7.5. This photo was taken during Dive 12 at Noyes Canyon.
